In this case study, data from proton NMR was combined with IR-MS to analyze cocoa samples and determine their country of origin.

Bruker has headed a study to find out lipoprotein subclass analysis based on proton NMR spectroscopy of serum samples or blood plasma, utilizing regression analysis of ultracentrifugation results.

NMR Spectroscopy Principles, Interpreting an NMR Spectrum and Common Problems In this article, we consider how nuclear magnetic resonance spectroscopy works, what it tells you and how it is used.

Suitable samples range from small compounds analyzed with 1-dimensional proton or carbon-13 NMR spectroscopy to large proteins or nucleic acids using 3 or 4-dimensional techniques. The impact of NMR ...

Solid-state NMR spectroscopy has the advantage of directly analyzing insoluble samples, making it a powerful tool for studying complex polymer systems. In this study, the researchers utilized an ...

*Aim*: Metabolite concentrations by in vivo magnetic resonance spectroscopy and ex vivo NMR spectroscopy were compared with excised normal human tissue relaxation times and tissue homogenate ...

Article Title Simple and User-Friendly Methodology for Crystal Water Determination by Quantitative Proton NMR Spectroscopy in Deuterium Oxide.

Hoye calls the technique No-D NMR, short for no-deuterium proton nuclear magnetic resonance spectroscopy [Org. Lett., 6, 953 (2004)]. As the name implies, the technique involves taking NMR spectra ...

In traditional proton—or 1 H—NMR, chemists use the chemical shifts of hydrogen atoms to help identify molecular structures.

The 19F nucleus is one of the key nuclei for NMR spectroscopy. Its NMR sensitivity is very high because of its 100% natural abundance and high frequency. In the pharmaceutical industry, organofluorine ...
